In this paper we present the Requirements Generation Markup Language (RGML). The RGML provides a formal specification mechanism for characterizing the structure, process flow and activities inherent to the requirements generation process. Within activities, the RGML supports the characterization of application instantiation, the use of templates and the production of artifacts. The RGML can also describe temporal control within a process as well as conditional expressions that control if and when various activity scenarios will be executed. The language is expressively powerful, yet flexible in its characterization capabilities, and thereby, provides the capability to describe a wide spectrum of different requirements generation processes.
